hello everybody
when paranitrophenyl acetate disolved in ethanol is diluted in phosphate=20
buffer (ph 7.0) with concentration ranging 50 to 200 mmole.litre-1 this one=
=20
becomes instable i.e the od increases, at room temperature or at 4=B0c,=20
protected or not of light
how can i stabilize pnpa in buffer at this ph ?
thank you in advance
=20
